Visitors to corn mazes across North America are finding a familiar and joyous figure in the winding labyrinth of tall stalks – Snoopy.

More than 80 farms in the US and Canada have teamed up with Peanuts Worldwide to create Peanuts-themed mazes to celebrate the beloved strip’s 75th birthday this summer and autumn.

A massive Snoopy rests on top of his doghouse in a maze at Dull’s Tree Farm in Thorntown, Indiana, and he is depicted gleefully atop a pumpkin at Downey’s Farm in Caledon, Ontario.

“All of these events helps keep my dad’s legacy alive,” says Jill Schulz, an actor and daughter of Peanuts creator Charles M Schulz.

“As someone who can’t even keep houseplants alive, the fact that they can do that with a corn maze and get the artwork right and create a fun experience for all ages is pretty incredible,” she adds, laughing.

The mazes — which span 35 states and provinces, from California to New York, Ontario to Texas — are expected to attract more than two million visitors.

Farmers are signing up for the free service because the mazes are part of the customer lure, in addition to things like hay rides, fresh produce and pumpkin carvings.

Each maze is designed for the size of the farm — from 1.5 acres to 20 acres — and are mostly corn but also sunflowers. They are custom created by the world’s largest corn maze consulting company, The MAiZE Inc.

The Utah-based Brett Herbst, who leads the company and who launched his first corn maze in 1996, says technology has only somewhat changed the way corn mazes are made.

“The first year we did it, we just used a weed whacker with a saw blade on it when the corn was fully grown,” he says.

“Now we do it when it’s short and we go in and either mow it or rototil it. We design it all on a computer, but most of it we actually just go draw it out on the ground by hand.”

He and his team have over the years designed mazes with everything from the faces of presidential candidates, Oprah Winfrey, zombies, John Wayne and Chris LeDoux.

This year marks the first time they have committed so fully to Charlie Brown and company.

“It’s very nostalgic and just seemed like a very natural fit from the get-go to embrace that with Peanuts,” he says.

“It’s harvest time. Its kind of become this iconic thing.”

There is an art and a science to maze building, a balance between maintaining the integrity of the image, but also making it a true maze where people can actually get lost in.

“That’s definitely a challenge there,” says Mr Herbst. “You want to accomplish both as much as possible.”

Peanuts made its debut on October 2, 1950. The travails of the “little round-headed kid” Charlie Brown and his pals eventually ran in more than 2,600 newspapers, reaching millions of readers in 75 countries.

The strip offers enduring images of kites in trees, Charlie Brown trying to kick a football, tart-tongued Lucy handing out advice for a nickel and Snoopy taking the occasional flight of fancy to the skies.

Phrases such as “security blanket” and “good grief” are a part of the global vernacular. Schulz died in 2000.

There is something timeless about corn mazes and that is what excites Jill Schulz so much. They offer children a chance to disconnect from their online life and celebrate something their parents did.

“It’s great to have an opportunity to just bring kids to events that are old school, because it’s also important for parents and grandparents to introduce something they loved to do as a child,” she says.

“I think we all need a little innocence for our children right now with all the technology out there. We need a little ’put down your phone and go out and have some good old fashioned, old school family time.’ I think that’s important.”
